To all whom t may concern:

' Be it known that I, WILLIAM l?. GArrs, a citizen of the United States, residing at Shreveport, in the parish of Caddo and State of Louisiana, have invented nevir an useful 'Improvements in Gras Burners, of

which the following 'is a specification.

lthe same are read in connection with the drawings, accompanying and forming part of this specification, in whiol1`z- Figure 1 is a top plan view of the burner yIconstituting the preferred embodiment of my invention, lsaid view being broken.

Figure 2 is adongitudinal vertical section oi the burner.

Figures 3 and 4 are transverse sections taken in the plane indicated b the lines 3-3 and 44, respectively, of i re 2.

Similar numerals of reference esifgnate corresponding parts in allof the views of the drawings.

My novel burner includes a body lof a propriete metal and appropriate shape, t e said body being closed at one end as designated by 2 and containing a main gas compartment 3, and air space 4 and a steam conduit 5. By preference the gas compartment 3, the air 's ace 4 and the steam conduit 5 are relative yarranged as best shown in Figure 4, the air space 4 surrounding the steam conduit t and being partly surrounded ,by the gas compartment 3. An `opening is provided in the outer portion of the body and in communication with the air space 4 tor the entrance of atmospheric air which is designed to adequately support combustion and at the same time lessen the liability oi the burner being unduly heated. In. the Wall oi the air space 4 are ports 7, and these ports Y are in alignment with nipples 8 preferably arranged in two series and with the nipples of each series atabout the angle illustrated to the nipples of the other series. The said nipples 8 are appropriately xed in the outer wall of the gas compartment 3 and are designed ,to receive gas from said compartment 3 and air from air space 4. It will also be noted that the steamconduit .Sis provided with minute apertures 9 in its Wall, said apertures 9 being substantially in 'draft -and to promote combustion.

alinement with the centers of the ports/7 and nipples 8.

A pipe 10v is connected to one end of the steam conduit 5, and a union 1l to one end of Bo the gas compartment 3, said union 11 being` connected in turnwith a T-coupling 12 the outer end of which is closed by an appro;

priate stuing box 13.A One arm of the T- coupling 12 is designed to be connected with 65 an appropriate source of gas supply, and the pipe 10 is designed to be connected with an appropriate source of steam supply. I would have it understood, however, that my novel burner is adapted to operate efiicient- 'lyon either' high or low gas pressure, the

embodiment illustrated is a burner of the steam jet type, but a cold boiler may be tired through the medium of the said burner without the assistance of steam. This will be better understood when it is stated that oonnections may be made so that gas will first pass through the pipe 10 and the conduit 5, the'arm 14 of the T-coupling 12 being at that time closed. In this use of the burner. after a few pounds of steam is raised in a boiler the arm 14 is opened, and the supply of gas to Jche pipe 10 is cut off and the proper amount of steam is permitted to pass through the pipe 10 for combustion of gas' '95 tothe best advantage. The nipples 8 maniytfestly may be made of any desired length'.

It will be apparent from the foregoing that my novel burner is adapted to operate on very low pressureand does not requirev a baile of any kind, the low pressure gas Y.being designed to enter through the arm 14 of thecoupling 12 and to pass from the compartment 3 to the nipples 8. The steam is jetted through the apertures 9 to indle 95 e opening 6 at the bottom of the burner provides for the assage of an ample amountvof air throughtlie burner with the result that combustion is adequately promoted and at the same time the burner is maintained i-n a comparatively cool state. I would also have it understood that m novel burner does not require'a brick ba e or target of any descriptlon and that it is quiet in opera- 10H5v tion.

In addition to the advantages ascribed to my novel burner it will be manifest that the burner is simple and inexpensive and is well adapted to withstand the usage to which '110 devices of corresponding character are ordi narily subjected. f

i' have specifically described the preferred embodiment of my invention in order to impart en exact understanding of Seid embodi- Vnient. I do not desire, however, to be understood as confining myself to the structure disclosed herein, my invention being defined by niy appended claims Within the scope of which changes may be made Without involving departure from my invention.

Having described my invention, what I claim and desire to secure by Letters-Patent, iszl. A burner including n steam conduit having apertures in its Well, mi air chamber entirely surroumlinp,l the steen conduit and having ports in its wall in nlignnient with said jet apertures and e gastroinartznent partly surrou'mling the nir Vohnmber and having nipples in communication with the interior thereof and arranged opposite the jet apertures sind the ports in the Wall of the nir ehnmbei; the smid nir channber havingr an opening for theentrance of air7 said steam compartment-and gas compertinent. beingblosed et one end and provided et their opposite ends with conduit connections.

2. A burner including a steam' conduit having jet apertures in its wall., an .air chamber entirely surroundingr the steam conduit and having ports in its Wall in alignment with said jet apertures, e gas co1npm-tment partly surrounding the air chamber sind having openings therethrough, nipples positioned in the last mentioned openings With their inner ends resting on the air vchannber and having communication with the ports therein and also connnunimtii'ig:r

with the gus compartment. seid nipples bein,"Y disposed opposite the'jet apertures, the seid air chambers having en opening ,for the entrance of nir and thev steam mnpartment and gais compartment being closed :it one en@ `und being: provided at their opposite ends with conduit connections.
